To all whom it may concern: gated formation as illustrated in Fig. 2 and 65 it known that I, J oznr Lerosznwsm, a carrying clips or anchoring devices 2 upon citizen of Poland, residing at Plymouth, in one endthereof that engage beneath the the county of Luze-rne vand State of Pennmine car rails 3 for {anchoring the same in s sylvran'ia have invented certain new and usep ful Improvements in Mine-Car Stops, of Pairs of vertical posts .hPlOjBCt perpen- 0 which the following is :a specification. .d-ieularly from the baseplate 1, the posts 4 This invention relates to certain new and being disposed zttf the outerkend of :the'base useful improvements in mine 0211 stops, and plate, while the posts .5 are disposed interhas for its primary object to provide a :de' mediate the ends thereof and are of greater vice that is disposed at one side of .a mine height than the end posts 1. A .pairofguide 05 car track and to be operated automatically hars fi having forwardly inclined upper sides by :a mine car for projecting a brake SllOeOl' 7 are-disposed between adj-scent posts 4 and block between the spokes of the mine car 5 while a forwardly inclined bar 8 extends wheel for braking the mine car and bringbetween the upper ends of the peirsof posts ing the same to rest. 7 v

A further object of the invention is to pro- .5 with the ends thereof'terminating adj acentvide a mine car stop that is automatically the inner end of the base plate l -and spaced operated by having a movable part thereof upwardly. therefrom as illustrated in Fi s..

arranged in the path of travel of a mine car 1 .and3. Another bar 9 extends between 518 and wherein achock block or brake shoe ear posts 4 and 5 intermediate the upper T ried by :ashiftable bar is thrown between the lower ends thereof and has a forward ex-o spokes of the mine car wheel. tension 10 projecting forwardly of the in- With'the :above and other objects in View termedlate post 5, the bars 9 and 10 being W that ill be om p ntd ring the course forwardly and upwardly inclined with the of the following description, the same 0011- upper inclined vlend of the bar section 10 0 sists of the novel form, combination and arlymg an a plane parallel with the upper inran-gement of parts hereinafter more fully clined sides f the bars 6.

The inner end of the Referring more in detail to the accomlever'15 is spaced from the end of the slot panying drawlng, there is illustrated a mine and a pulley 17 is rotatably mounted upon car stop embodying a base plate 1 of elonthe pin 18 between the inner ends of the 4' and 5 .and projects forwardly of the post 70 ment of the cable 21.

arms 14. Another pulley 19 is journaled in an opening 20 provided in one of the intermediate posts 5 that is alined with the outer end of the arm 13 as shown in Figs. 2 and 4 and a cable or cord 21 secured at one end to the outer end of the arm 13 passes over the pulleys 19 and 17 for attachment to the inner end of the lever 15. As shown more clearly in Fig. 3, guides 22 are carried by the post 5 and bar 6 for directing move- The outer end of the lever 15 carries a head 23 that is pivotally mounted thereon as at 24 as shown in Figs. 1 and 2 so that upon shifting movement of the head 23, the apparatus may be rendered either operative or inoperative for contacting by a part of the mine car C.

A chock block or shoe 25 of the form best illustrated in Figs. 1 and 3 has one pointed end thereof positioned in the notched outer end 26 of the rod 11 while the forward end 27 0f the lock 25 is provided with a cushioned surface to prevent injury to the spokes of the mine car wheel. When the rod 11 is retracted as illustrated in Fig. 1, the block 25 is supported at its inner end by the notched end of the rod 11 while the outer end thereof rests upon the support 28.

With the device positioned as illustrated in Fig. 1, and with the head 23 extended, a mine car approaching the apparatus will have an appropriate part there adapted for contacting the head 23 for moving thelever 15 upon its pivot 16, the cable connection 21 between the inner end of the lever 15 and the arm 13 carried by the rod 11 will cause the rod 11 to be moved to the position shown in 3 for throwing the chock block 25 between the spokes of the mine car wheel, the rod '11 being elevated as illustrated by the link connection 12 betweensaid rod and the bar 10 and also by reason of the fact that the arm 13 rides upwardly upon the inclined upper face 13 of the side bar 6. When it is desired to render the apparatus inoperative, the head 23 is shifted upon its pivotal mounting 24. to displace the same out of the path of movement of the mine car.

VVhile there is herein shown and described the preferred embodiment of the present invention, it is nevertheless to be understood that minor changes may be made therein without departing from the spirit and scope of the invention as claimed.

What is claimed is 1. In a mine car stop, a frame structure associated with a mine car rail, a rod slidably associated with the frame structure, a brake shoe shiftable between the spokes of a car wheel upon movement of the rod and means operated by a mine car and connected to the rod for shifting the same.

2. In a mine car stop, a frame structure associated with a mine car rail, a rod slidably associated with the frame structure, a brake shoe shiftable between the spokes of a "11- wheel upon movement of the rod, means operated by a mine car and connected to the rod for shifting the same, and means associated with the rod for raising the same during shifting movement.

3. In a mine car stop, a frame structure associated with a mine car rail, a rod slidably associated with the frame structure, a brake shoe shiftable between the spokes of a car wheel upon movement of the rod, a

lever pivoted on the frame structure, a cable connecting the lever to the rod, and means carried by the lever adapted to be placed in the path of movement of a mine car.

4:. In a mine car stop, a frame structure associated with a mine car rail, a rod slidably associated with the frame structure, a brake shoe shiftable between the spokes of a car wheel upon movement of the rod, a lever pivoted on the frame structure, a cable connecting the lever to the rod, and a head pivotally mounted at the outer end of the lever adapted to be placed in the path of movement of a mine car.

5. In a mine car stop, a frame structure associated with a mine car rail, a rod slidably associated with the frame structure, a brake shoe shiftable between the spokes of a car wheel upon movement of the rod. means operated by a mine car and connected to the rod for shifting the same. said frame structure including a pair of vertically spaced inclined bars and links carried by the rod associated with the bars for elevating the rod during shifting movement.

In testimony whereof I afliX my signature.
